Paint Coverage Formula & Calculations

Basic Coverage Formula

Coverage Area = Base Coverage × Paint Quality × Finish Factor × Surface Factor

This formula accounts for all variables affecting paint coverage, providing professional-grade accuracy.

Coverage Factors

Base Coverage: 350-500 sq ft per gallon (varies by paint type)
Quality Factor: Economy (0.85) to Designer (1.25)
Finish Factor: Flat (1.0) to High-Gloss (0.80)
Surface Factor: Smooth (1.0) to Brick (0.60)

Common Coverage Examples

1 Gallon: 350-500 sq ft (1 coat)
1 Quart: 87-125 sq ft (1 coat)
5 Gallons: 1,750-2,500 sq ft (1 coat)
Primer: 300-400 sq ft per gallon

Important Calculation Notes:

  • • Always add 10-15% extra paint for touch-ups and waste
  • • Dark to light color changes typically require 2-3 coats
  • • Textured surfaces can reduce coverage by 15-40%
  • • Premium paints often provide better coverage per gallon

Frequently Asked Questions

How much area does 1 gallon of paint cover?

Typically, 1 gallon of paint covers 350-500 square feet depending on paint quality, surface texture, and application method. Our paint coverage calculator provides precise estimates based on your specific conditions.

What is paint coverage per gallon for different finishes?

Flat paints typically offer the best coverage (400-500 sq ft), while high-gloss finishes may cover 350-400 sq ft per gallon due to their density and application requirements.

How do I calculate paint coverage for 1 quart?

Paint coverage for 1 quart is approximately 87-125 square feet (1/4 of gallon coverage). Use our calculator by entering 0.25 gallons to get precise quart coverage estimates.

What affects paint coverage the most?

Surface texture has the biggest impact on coverage. Smooth surfaces maximize coverage, while textured or porous surfaces can reduce coverage by 15-40%. Paint quality and application method also significantly affect results.

How much coverage do 5 gallons of paint provide?

Five gallons of paint typically covers 1,750-2,500 square feet in one coat, making it suitable for large rooms or entire small homes. Always factor in multiple coats for color changes or premium finishes.
